This invention relates to composing systems and apparatus, and particularly to apparatus for preparing a control strip for the automatic control of composing machines.

are provided with matrices consisting of small brass units carrying indented characters in their edges, which are of different thicknesses, due to the fact that the characters vary in width. To

lo produce lines of type, the matrices are assembled into a line of predetermined definite length before the casting operation is performed, the number of matrices necessary to complete a line varying with the particular matrices already assembled. The length of the line, therefore, is dependent upon the thickness of the several characters or matrices comprising the line.

It is necessary, during the preparation of a control strip representing lines of composed matter for the production of the slugs or lines of type, to totalize the various thicknesses of matrices so that the operator will be apprised. of the length of line remaining available as each key is operated, and can thus judge the justifiability of .-the line.

The principal object of the present invention'is to provide a counting-device which is capable 'of positive, efficient, and rapid operation.

To achieve the above and other objects of the gorinvention, the keyboard perforator and counter, according to Patent No. 2,059,250 issued to H. L. Krum is modified to embody the features of the present invention. In addition to the Krum patent, reference should also be had to Patent No.

2,083,570 granted June 15, 1937 to E. S. Larson et al., and E. S. Larson, respectively, for a full and comprehensive disclosure of a keyboard perforator and counter in which the features may-be 40 embodied. v

In accordance with the present embodiment of the invention, the keyboard includes key le vers, arranged in a manner characteristic of typewriters, which operate through a permutation selector mechanism contained in the housing of Composing machines of the linecasting type cording to the rod selected, like rotation is imparted to a spiral gear operatively associated with'the counting barrel. Through a suitable gear train, variable motion is imparted to a matrix pointer associated with an indicator dial.

As .the keys are depressed, the matrix pointer will be moved through various cumulative distances corresponding to the widths or thicknesses of the matrices represented by the keys. The variable motion imparted to the matrix pointer may be adjusted'for different fonts of type by interposing between the key levers and the selector mechanism for the counting device an interchangeable code bar unit comprising a plurality of pairs of elements, one pair allotted to each key lever and operable thereby. Means is provided for shifting the counting code bar unit from its lower case to upper case positions and vice versa by the shift and unshift key levers respectively, and also to provide means for insuring the prompt return of the "matrix pointer to its beginning-ofline position during a single revolution of the release operating clutch mechanism.

A more comprehensive understanding of the present invention may be had from the following description, taken in conjunction with the accompanying drawings, wherein like reference characters represent similar parts throughout the several views.

the present invention. In Fig. 1 a plurality of key levers H are pivoted on a common rod (not shown) and are normally held in a horizontal position by individual springs (not shown). These key levers extend over a number of pairs of selector bars l2 and It included in the perforator selector unit indicated generally by the numeral l4, and the pairs of bars l5 and It included in the selecting unit of the counting mechanism indicated generally as ll. Each key lever II is arranged to depress one of the bars |2--|3 or I 5--|6 of each pair of bars. Through the medium of rocker arms I 8, the bar |2 or l3 lifts the other bar of the pair to reciprocate longitudinally a bar It cooperatively associated with and subjacently disposed to each pair of bars 12 and I3 to impart corresponding movement to the associ-' ated pivoted member 2|. The members 2|, as disclosed in said patent, control the operation .of punch interference elements 22 in the tape perforating unit 23. Bars I!) are set in characteristic combinations, and for this purpose, bars I 2 and I3 are provided with notched upper edges, the bars of each pair being complements; that is, the high portions of one bar are disposed opposite the low portions of the other bar of the same general pair.

Interposed between the series of key levers H and the counter selector unit I1 is a removable and interchangeable code bar unit, indicated generally by the numeral 24, which carries therein a plurality of pairs of coded elements 25. In this manner, there is allotted to each of the key levers H a pair of coded elements 25 which coact with the pairs of permutation bars l5 and I5 of-the counter selecting unit H.

The removable code bar unit 24 for carrying the pairs of coded elements 25 comprises a channel-shaped member having a webbed-portion 25 and side walls 21 and 28,'which are, in turn, pro-- vided with flanges 29 and 3 respectively, (Fig. 4.) The web 2 5 is provided with rectangular apertures 32 (Fig. 3) to guide the vertical projections 33 and 34 of the coded elements 25. Theflanges 29 and 34 have notches in vertical alignment with the apertures 32 to insure the vertically guided movement of the coded elements 25.

The coded elements 25 areretained in their uppermost positions by Springs 35, each of which, as indicated in Fig. comprises a coil spring having its extremity extended tangentially thereto and oppositely directed therefrom, which, in turn, terminates in laterally disposed portions -35 (Figs. 1 and 4) adapted to coact with the inner surface,respectively of projections 33 and 34 of the coded ele ments 25. These springs 35 are mounted upon a rod 37 carried in the unit 24. A guide member 38 guides the extremities of the springs 35. With retention springs accordingto this arrangement, the code elements 25 are readily removable and lnsertable, and are arranged asa floating construction. To insert a pair of code elements 25, they-need only be assembled by means of their dowel pins and'slid up.into the notches in flanges 29 and 3| and into the corresponding apertures 32 until portions 35 of spring35 engage the undercut portions of projections 33 and 34, the spring then acting to urge the pair of elements 25 upwardly to press the'shoulders 39 against the flanges 29 and 3|. The pair of elements 25 is readily removable by urging the pair downwardly under slight pressure, thus flexing-the tangentially extended portions of the spring 35 until the ends 36 thereof slip over the inner. apical individual I retention portions of projections 33 and 34 of the code elements 25.

A shiftable carrier or cradle, indicated generally by the numeral 4|, controls the movement of the removable code bar unit 28 from the shift or front position to the unshift or rear position, and vice versa. Carrier 4| consists of a framework comprising a pair of channelled guides 42 and 48, Fig. 4, suitably spaced apart to provide guideways for the insertion and removal of code bar unit As shown in Fig. 4, the carrier 4| is mounted at its'four corners on corner posts 44 which, in turn, are supported upon links 45, pivotally connected to the posts 44 and brackets 46, mounted on base portion. The shifting of carrier 4| is accomplished in parallel motion manner by shift mechanism which, according to the present invention, is controlled by the shift key lever 48 and unshiii key lever 49, Fig. 1.

In order to associate the proper projections 58 on the counting code elements 25 with the proper counting selector bars I5 and IE, it is necessary toshiftthe position of the code bar unit 24 from right to left, or vice versa, as viewed in Fig. 4, which is from front to rear, or vice versa, of the keyboard apparatus. This movement is accomplished, as previously indicated, by means of the shift and unshift levers 48 or 49, having reference to Fig. 1. Suitably carried in the portion 4'17 are bell cranks 5| and 52 pivoted at 53 and 54, respectively. The horizontal arms of bell cranks 5| and 52 are adapted to coact with shift and unshift key levers 48 and 49, and the depend-- ing arms of bell cranks 5| and 52 are pivotally connected to a bar 55 which, in turn, is pivoted at each end to bell crank levers 56, also pivotally carried on portion 47. The other arms of the bell crank levers 55 are pivotally articulated to downwardly projecting studs or pins 5? on the carrier 4|. With this arrangement, the shifting of the carrier 4| is accomplished by depressing eitherthe shift key lever 48 or the unshift key lever 49 to rotate their individual bell cranks or 52. Assuming that the unshift key lever li! is depressed, bell crank 5| will be rotated in a counterclockwise direction to move bar 55 rightwardly, whereupon bell cranks 56, articulated to bar 55, will be rotated counterclockwise. The rotation of bell cranks 56 will, through pins studs 51, cause the carrier 4| to be shifted rearwardly upon the supporting links 45. Conversely, when the shift key lever 49 is depressed, bell crank. 52- will be rotated in a clockwise direction to move the bar 55 leftwardly. whereupon bell cranks 56 will be similarly rotated which, through studs 51', will cause the carrier 4| to be shifted frontwardly upon links 45.

When any key lever is depressed, the selector bars l5 and IE will be moved in accordance with. the location of the projections 58 on the code elements 25 to cause the movement of the permutation bars 59 (which are operatively associated with the pairs of selector bars I5 and It in a manner similar to the association of bars H) with selector bars I2 and I3) in various permutations. As indicated in Fig. 4, the code projections 58 on one of the elements 25 are effective in one position, and the projections 58 on the other element 25 of the pair are effective in another position. The carrier 4| is shown in Fig. 4 in its right-hand or unshift position, in which position, the projections 58 of the rear element 25 are observed as being in cooperative relation with the selector bars l5 and Hi. In the position shown, the projections 58 of the front element are observed. asbeing outof cooperative relation with bars I5 and I6. When the carrier 5| is moved to the shift or leftward position, the projecti0ns58 on the front element 25 will be disposed in cooperative relation with the bars iii The bars 59, Fig. 4, as fully described in Patent No. 2,059,250, are operatively connected to a corresponding series of Y-shaped members 6|, (Fig. 1) which are adapted to be positioned in accordance with the operation of the permutation bars 59 to control the setting of a plurality of notched discs 62, forming part of a code disc selector, in-

dicated generally by the numeral 63. Individual.

to each of the members 6| and nctchedcode discs 62 is a transfer lever 64, which is pivotally mounted on a rod 65 carried in a bracket (not shown) operated, in a manner described in Patent No. 2,059,250, to reciprocate the transfer levers 64 vertically. Upon reciprocation, the transfer le-- vers 64 will be moved into cooperative relation with the Y-shapedmembers 6|; that is, whether the members 6| are swung to the right or left, as viewed in Fig. 1, the abutments 69 of the transfer levers 64 will engage "or be free of one or the other of the abutments I8 onthe upper end of Y-shaped members 6| to cause the discs 62 to be rocked in either a clockwise or a counterclockwise direction. With the Y-shaped members 6| operated in varying permutations in accordance with the movement of the permutation bars 59, the discs 62 will likewise be rotated in varying permutations and will, for, each permutation, cause an alignment of notches formed in the periphery of the discs.

Cooperating with the notches inthe discs 62 are a plurality-of rods 66 arranged with anti-friction rollers 61, there being'a rodindividual to each set of aligned notches. Each of the rods 66 is centripetally biased by an individual spring .68. In this manner, the rods 66 tend to moveradially toward a common center into the notches of the discs 62, but inasmuch asthenotches arearranged so that for each setting of the discs, only one group of notches willbe in transverse alignment, only one of the rods 66 for each selection will move into the notches. Also, the notches in the discs 62 are arranged so that when the discs are moved for a subsequent selection, the previously selected rod 66 will be cammed outwardly against the action of its associated spring 68. Carried on the right-hand end of each of the rods 66 is a stopmember 69 (Fig. l), which slides in slots formed in a circular member I I.

To the right of the code disc selector 63 (as viewed in Fig. l) is a counting barrel or rotor 12 forming a part of the counting mechanism, which is rotated by power communicated from a continuously rotating motor (not shown), through a friction clutch 13. The counting unit I2 comprises a plurality of circumferentially arranged slides I4, which are longitudinally slidable and adapted to coact with the stop members 69 to determine the degree of rotation of unit 12, and any of the slides I4 which are found in the zero position are operated invariably by a lever (not shown), while a previously. operated slide is simultaneously restored to its normal or non-operated position by a collar 15 to accomplish, through the coaction of an operated slide 14 and a selected stop member 6.9, the incrementally progressive movement of the counting unit 12. The. counting unit 12 includes a shaft 16 on which is formedv a worm I1. Attention is directed hereinto the structural feature of: counting unit I2 in that it is of a very small diameter, thereby permitting a high speed of rotation. By having the parts near the axis of rotation, the centrifugal action is reduced, and the amount of inertia is materially less, which makes possible the rotation of the parts at very high speeds.

As previously mentioned, the slides 14 cooperate with the rods 69 to arrest the rotation of the counting unit I2, which is driven, through friction clutch 13, to cause a corresponding degree of rotation to worm TI. The rotation of the worm H, which meshes with a gear I8 secured to a shaft '39, causes the corresponding angular rotation of a shaft 8|, through gears 82 and 83. A worm 84 is fixed to the other extremity of shaft 8| (Fig. 2) and meshes with a worm wheel 85.

- As shown in Fig. 1, the indicator comprises a bracket 81, which carries 'pivotally thereon, through the instrumentality of member I69, a dial 88, which is provided adjacent to its outer arcuate edge with a scale or series of graduations representing increments of a maximum length of line. The reverted end of a matrix pointer 86 moves along this edge of the dial from left to right, towards zero, in response to the totalization of the matrix thicknesses by the counting mechanism. Thus, the distance from thepointer 96 to zero indicates the amount of space left in the line to be filled with matrices if the line contains no space bands. However, if space bands are inserted in the line, the spaceremaining to be filled varies with the number of space bands inserted. Consequently, to indicate the justifiability of the composed line, a pair of space band pointers 89 and 9| are provided, the distance between the pointers 89 and 9| indicating the amount of expansibility of the space bands.

In the embodiment shown, the dial 88 is articulated to the minimum space band pointer 9|, through a pin 92, and is movable with said pointer. The space left in the line to be filled when space bands are inserted is represented by the distance between the matrix pointer 86 and any point between space band pointers 89 and 9|. The manner of effecting the differential or proportional movement of pointers 89 and 9| toward the left (from their zero position) is fully set forth in Patent No. 2,059,250.

As shown in Fig. 2, the matrix pointer 86 is associated with the scale 88, and is separated from the counting clutch to enable the introduction of an adjusting mechanism for varying the movement, or rate of deflection of the matrix pointer 86 with respect to the fixed movement of the counting mechanism 12, to permit direct pica measurement of the type instead of limiting the measurement of lines to keyboar ems. The

-matrix pointer 86 is mounted for rotation on a pivot stud 95 fixed to the bracket 81. Also associated with the matrix pointer 86, to rotate therewith on shaft 95, is a pinion 91.

The counting clutch, as shown in Fig. 5, comprises a shaft 98, which terminates at one end in a flange or disc 99, the other end of which is threaded to receive a nut IUI. Shaft 98 is carried in a flanged sleeve member I92, and attached to the flange I95 of member I92 is the worm gear 85. The assembly, comprising shaft 98 and sleeve I82, is mounted in a bearing or bracket I83 carried on the base I94 (Fig. 2). Interposed between the fiange 99 and the flange I95 are a pair of friction discs I96 and an intermediately disposedgear I61. Pressure is imparted tothefriction discs I06, to constrain the gear I01 for rotation with worm gear 85, by a compression spring I00, which is compressed between the nut IOI and a nut I09 carried on the sleeve I02. A friction washer III is disposed between the nut I09 and the vertical bearing portion of bracket I03. With the arrangement so far disclosed, the rotation of the counting unit 12 is imparted, through gears 19 and 82 on shaft 19 and gear 83 on shaft 8| to worm 84, to rotate worm gear 85, to impart, in turn, rotation to the gear I01.

Meshed with gear 91 is a vertically disposed rack member H2, carried in guide brackets H and I I3 mounted on frame 05, Fig. 2. Carried on rack I I2 is a stud I I4 which coacts pivotally with one end of a lever II5, adjustably fulcrumed at 0. Fulcrum IIO comprises a block member II1 (Fig. l) and receives a screw member I I8 in such a manner that the block H1 is adapted, when screw I I8 is turned by the knurled cap I20, to travel along a diagonal slot I I9 (Fig. 2) in bracket 96. Lever H is provided with a slot I2! to provide, together with slot H9, a means for adjustably controlling the vertical movement of rack II2. The left end of lever H5 (as viewed in Fig. 2) cooperates with a stud I22, carried on a rack member I23 suitably guided for vertical movement on the bracket 99. Rack I23 meshes with the gear I01 associated with the worm gear 85 (Figs. 2 and 5) in such manner that, when the gear 85 is rotated under the control of the counting mechanism 12, rack I23, through the instrumentality of friction discs I05 and gear I01, is given a downward movement, which movement, through stud I22, is imparted to lever I I5, causing it to rotate in a counterclockwise direction about fulcrum I I0 to elevate the rack I I2, which causes, through gear 91, the matrix pointer 85 to move toward the left (Fig. 2).

A lever I25, pivoted at I on bracket 95 and actuated by a spring I21, is provided to effect the return of rack I23 to its uppermost vertical position when the clamping effect of flange 99 on gear I 01 is relieved.

To effect the prompt return of the rack I23, and hence matrix pointer 85, to its beginning-of-line position, the present invention provides a booster or quick return means, comprising a bell crank lever I20, pivoted on shaft I29 carried in a brack et 90 secured to bracket I03. Bell crank I20 has an arm I3I, to the end of which is connected one end of a spring I32, the other end of which is connected to lever I 25. The other arm I 33 of bell crank I20 cooperates with the depending arm I34 of a bell crank lever I35 pivoted at I30. Lever I35 is normally employed to unclamp the counting clutch, through the medium of its vertical projection I36. The unclamping of the counting clutch is effected through link I31, pivoted at the extremity of the horizontal arm of lever I35, and pivotally articulated to a lever I30, pivoted at I39 to a bracket MI, mounted on base I04 (Fig. 2). As shown in Figs. 1 and 8, the extremity of lever I38, opposite to the link I31, is provided with a follower roller I42, adapted to coact with a cam I43, associated with a clutch I44, carried on the operating shaft I45. Also, asso' ciated with clutch I44 is a clutch throw-out lever I40, with which is associated a vertical latch arm I41, which functions to disengage the clutch throw-out lever I 40 from stop I 00. Latch I 41 is carried at the extremity of a lever I48 which, as shown in Figs. 2 and 8, is pivoted on pivot I39. To the extremity of lever I48, opposite to that at which latch I41 is carried, is pivoted a link I40 (Figs. 2 and 8), which provides an interconnection between lever I48 and the key lever I! (Fig. 8) assigned to the elevator or end-of-line signal.

The cam I43, as shown in Fig. 8, carries a pin I40 aligned in its rotation with an arm I50 complementary to the latch arm I41. The pin I40 is arranged with respect to the clutch throw-out cam surface I00 to operate the member I50 just prior to the completion of the cycle of rotation of the cam I43 and causes the rotation of the latch member I41 and the restoration of the lever I46 to its normal position or in a position to arrest the rotation of the driven portion I54 of clutch I44 and cause it to move axially of the shaft I45 or to the right, as viewed in Fig. 1. The purpose of the pin I40 and the arm I is to ensure that thecam I43 will invariably be ar rested for each cycle of rotation. In other words, the clutch I44 is referred to as a single revolution clutch in that for each release of the driven portion I54, it makes a single complete revolution before it is disengaged from the driving portion I which is fixed to the shaft I45.

Accordingly, upon the depression of the elevator key, downward movement will be imparted to link I49 to cause lever I48 to rotate counterclockwise (as viewed in Fig. 2) to raise lever I41 (Fig. 1) to effect the release of clutch throwout arm I 46, and to permit the engagement of clutch I44 to cause the rotation of cam I43 through a single cycle of rotation. Through cam I43 and follower roller I42 (Fig. 1), clockwise rotation is imparted to lever I38 (as viewed in Fig. 2) to cause, through link I31, the clockwise rotation of bell crank I35, which, through shaft 98 (Fig. 5), causes the counting clutch to become unclamped. Simultaneously with the unclamping function, the depending arm I34 of bell crank I35 acts on arm I33 of lever I28 to cause lever I28 to be rotated counterclockwise, which movement, through arm I3I, stretches spring I32, and thus, through spring I32, causes lever I25 to rctate in a clockwise direction. It is understood that the motions just described are sharp and sudden, and hence the momentum imparted to lever I25, through spring I32, is such as to impart a sharp upward movement to rack I23, to effect the return of rack I23 to its normal or beginning-of-line position during the time that gear I01 is unclamped, and before it is again clamped.

The return of matrix pointer 30 is effected by means of a spring I5I, through a lever I52, which is provided at its extremity with a gear segment I 53, which meshes with a gear 91 associated with matrix pointer 86. Thus, when rack I23 is returned to its vertical stop position, lever H5 is free to be rotated in a clockwise direction by the action of spring I5I, which causes lever I52 to rotate in a counterclockwise direction to impart clockwise rotation to matrix pointer 85 and gear 91. The clockwise movement of gear 91 causes rack II2 to move downwardly and, through stud II4, imparts clockwise rotation to lever II5.

Rack I23 cooperates with two vertical stops; namely, a fixed stop I55 and an adjustable stop I 55 (Fig. 2). The fixed stop I55 comprises, in the present embodiment, a set screw mounted in lug I58 on bracket 96, and is set so that when rack I23 abuts against stop I55, the slots I59 and I2I are parallel and coincident. The adjustable stop I58 is adapted to mesh with an adjusting screw I59, supported vertically in brackets I64 and I65, and provided with a cap portion I66. As indicated in Figs. 6 and '1, adjustable stop I55 comprises a block provided with a a coiled spring I69.

nal shifting of bar I9 individual thereto.

threaded groove on its edge to correspond to the screw I 59 so that block I56 can be drawn,.at will, out of engagement with screw I59. To enable the block I56 to be readily and easily withdrawn from the screw I59, a pair of cam levers I61 are provided which are pivoted to stem I68 integral with block I56. Levers I61 are normally held in the position shown in Fig. 6 by means of When the levers I61 are pinched or drawn together to the position shown in Fig. '7, the block I56 is withdrawn from engagement with screw I59 and in this manner block I59 may be shifted vertically to achieve a quick adjustment of the adjustable back stop. After the desired stop position is approximated, the cap I66 (Fig. 2) is turned to effect, through screw I59, a micrometer or fineadjustment of block I56. As noted in Fig. 2, rack I23 is provided with a lateral portion I1I which abuts the adjustable stop I56.

Modification In Figs. 3 and 4 is shown a modified form of the shift mechanism for shifting the counting code bar unit, under the control of an additional pair of selector bars I2 and I3 in the perforator selector unit I4. As indicated in Fig. 3, a bar I9 is provided with angular members I6I, which are pivotally articulated to a pair of bell cranks I62, pivotally carried on base 41, the other arm of the bell crank being pivotally articulated to studs I63 (comparable to studs 51 in Fig. 1).

Thus, upon the depression. of the shift or unshift key levers, the pair of bars I2 and I3, associated with the shift mechanism, is operated to cause, through rocker members I8, the longitudi- Thus, the depression of the shift key lever will cause bar I9 to be shifted rightwardly, as viewed in Fig. 3, to impart counterclockwise rotation to bell crank I62, thus causing, through studs I63, the carrier II to be moved rearwardly. Then, when it is desired to shift the carrier M to its other shift position, the opposite shift key will be operated, which will cause, through rocker arms I8, the bar I9 to be shifted leftwardly (Fig. 2) to cause bell cranks I62 to be rotated clockwise, thus causing the carrier 4| to be moved forward.
